Phlinoside F,a New Phenylethanoid Glycoside from Phlomis angustissima

摘要

From the overground parts of Phlomis angustissima,a new phenylethanoid triglycoside,beta-(3-hydroxy,4-methoxyphenyl)ethyl-OMICRON-[beta-xylopyranosyl(l->2)-alpha-rhamnopyranosyl-(l->3)] - OMICRON-4-OMICRON-feruloyl-beta-glucopyrano-side,named phlinoside F,was isolated along with the known compounds alyssonoside,samioside,lamiide,auroside,naringenin,and syringaresinol-4-OMICRON-beta-D-glucopyranoside.The structure of the new glycoside was elucidated by spectroscopic methods.
